A man found a USB flash drive with detailed information about Heathrow Airport security and anti-terror measures. The USB stick, which contained 2.5GB of data, was neither encrypted nor required a password to access it. The drive was reportedly found in leaves on the street by an unemployed man; he plugged it in at a library where he was using a PC to search for a job. The stick contained 76 folders, packed with maps, documents and videos, even security measures to protect the Queen and the route she takes when using the airport.”]
